Corsair TWINX2048-3500LL PRO

Performance @ 2-3-2-6

Next, we continued testing with SiSoftware's SANDRA, the System ANalyzer, Diagnostic and Reporting Assistant, but we manually set the memory timings on the Corsair TWINX2048-3500LL Pro modules to 2-3-2-6 (CAS Latency = 2T, RAS to CAS Delay (tRCD) = 3T, Row Precharge (tRP) = 2T, Active to Precharge Delay (tRAS) = 6T). Then we raised our system's HTT clock until it was no longer stable. Our goal was to find the maximum stable clock speed that the modules could attain, without issue. For the sake of comparison, we did the same with our reference Kingston and Corsair Pro modules as well. For all of our overclocking tests, we cranked the memory voltage up to 2.9v via the system BIOS.

Performance Comparison with SiSoft SANDRA 2005

Raw Bandwidth

The TWINX2048-3500LL Pro memory kit was able to reliably hit DDR446 while running with its rated latency settings of 2-3-2-6, which was a bit higher than either the Kingston or other Corsair kit was able to achieve. This was somewhat expected though, considering the TWINX2048-3500LL Pro sticks required slightly more relaxed settings. While overclocked, all of the kits posted marginally higher bandwidth, with increases hovering around 500MB/s.
